名为“日期”的列和 EF Core 7 迁移

Question

我们的实体具有以下属性：

public DateTime Date { get; init; }

然后我们将其重命名为：

public DateTime DateUTC { get; init; }

在

Up(MigrationBuilder migrationBuilder)

方法中，我们有：

migrationBuilder.RenameColumn(
  name: "Date",
  table: "VirtualAccountStatus",
  newName: "DateUTC");

迁移无法运行并出现以下异常：

应用迁移“20220422111129_Rename_VirtualAccountDateField”。执行 DbCommand 失败 (67ms) [Parameters=[], CommandType='Text', CommandTimeout='30'] EXEC sp_rename N'[VirtualAccountStatus].[''Date'']', N'DateUTC', N'COLUMN' ; Microsoft.Data.SqlClient.SqlException（0x80131904）：参数@objname不明确或声明的@objtype（COLUMN）错误。

我认为这是因为 EF Core 7 不喜欢我们有一个名为

Date

的列（也许是保留关键字？）

我怎样才能克服这个问题，以便重命名该字段并使迁移满意？

Answer 1

作为解决方法，可能会将迁移更改为：

migrationBuilder.Sql("EXEC sp_rename N'[VirtualAccountStatus].[Date]', N'DateUTC', N'COLUMN';");
